Sarah Palin released her tax records for the years of 2006 and 2007, showing her income, and how much she paid in income taxes. She has given more to charity compared to Joe Biden's combined totals since 1998.

According to the Reuters report, the 14.9 percent paid as income tax is comparable to what "most Americans of their income level pay."

The USA Today did receive an email from Biden spokesperson, David Wade, stating the Bidens "also contribute to their favorite causes with their time as well as their checkbooks."

Nationally, more than two-thirds of U.S. households reported giving to charity in 2004, with average contributions of $2,047 that year, according to a study released in January by the Center on Philanthropy at Indiana University. Those households who gave to charity averaged donations of about 3% of their income, says Patrick Rooney, the center's interim executive director.
